I couldn't disagree more.
My example did not use fractional exponents.
Do you disagree that 2^3*2^4=128?
Do you disagree with the identity x^a*x^b=x^(a+b)?
I gave an example of how to multiply...

You're talking about permutations. N items can be arranged in n! Ways (where ! Is the symbol for factorial).
For example, 5 items can be arranged in 120 ways and 20 items can be arranged in...

juhi2011, if you think my answer is wrong please provide the right answer to prove that you are correct so that I may have a chance to disagree with you.

This should be a new question. However, just like with normal numbers you need to get to a common denominator. For example, \frac 1 {2x} + \frac 1 x = \frac 1 {2x} + \frac 2 {2x} = \frac {1 + 2} {2x}...

jiten55 seems right to me. Substitute x=1 in and you'll see it's right.
5^{1+3}5^{1+1}=5^45^2=62525=600

We won't do your assignments for you. If you have any questions on how to implement a sort function we can answer that

I think a faraday cage will block magnetic fields as well as electric fields so surrounding the spoon with a metallic sphere should also work.

yeah, try another object which is also attracted to the magnet. I believe that if you put an iron sheet between the magnet and the spoon the iron sheet will conduct the magnetic lines of force...

Sorry kesavan, I guess none of us are really familiar with the hope apparatus. I've found few references to it online and none of them seemed to really help me answer your question. Do you know of...

Please review your class notes and/or textbook for this answer. We do not do your homework for you.

Since I'm an expert I'll answer your questions:
Capuchin,last Thursday, in his bedroom, wouldn't you like to know. ;)
Seriously, this is like asking who discovered fire, or the wheel. The article...

jiten55 is essentially correct. One extra thing to be aware of is that since this will result in a quadratic equation you'll end up with two mathematic solutions for x. However, only one of them will...

"twenty minus the product of 4 and a number x is less than four" and you came up with "(xy)x^212xy+20y^2)"??
you can't be serious, that equation must be for a different problem.
lets work it...

Do you have a question or are we supposed to guess?
Whatever your question, show your work and we'll help you out.

what's the question? There are an infinite number of equations in terms of x that would return 35 when x=7. There are even an infinite number of linear equations with that property.

I think your initial equations will transform into this (if this helps you) but I haven't done matrices in a while:
\left[ \begin{array}
2 \\
3
\end{array} \right] x +
\left[ \begin{array}
5...

Draw a picture, look at the angles, try drawing a line which goes through point B and perpendicular to line AC.

The problem you have listed is
3.6P_0+83.3=\left(3 \frac 4 7\right)P_0+46.4
and you want to solve for P0.
First I'll convert 3 4/7 to 3.57
3.6P_0+83.3=\left(3.57\right)P_0+46.4 \\

Oooh, sorry capuchin. My answer gave it away much more than your more helpful advice!

is your equation
59dB=20\log {\frac 1 {{\left(1+{\left(\frac F {Fc}\right)}^6\right)}^{\frac 1 2}}}
And what base is your log? I'm assuming base 10. So log(10)=1.

assuming it's a convex polygon the equation for the sum of the interior angles in degrees is (n2)*180 where n is the number of sides.

can't you start with the fact that a^{\log_a b}=b? After that it's all algebra I think.

Not sure what you mean. When n=2 n^4+1=17 which IS prime.
Initial investigations (n=1.. 6) indicate that it IS prime if n is an even positive integer.

Thanks for showing your work! :)
Since you want to solve for when x=4 you don't need to do it the hard way and pull the x all the way through. Just substitute the 4 straight away and it will be...

Can you show your work so far?

you've got the right idea. You just used the wrong data. You said that the side was 7\sqrt 2, not 7. Replace your 7s with the real side length and you'll be good to go.

kesavan, you're certainly right that the energy will be distributed across 2 prongs. I think I had some additional complication in mind when I wrote that but I can't remember it now.
Another idea...

f(x) means evaluate the function f at the point x
g(f(x)) means evaluate the function g at the point which is the result of evaluating the function f at the point x.
essentially you determine f(x)...

What's the probability that 1 gives a poor rating?

you have enough information.
The probability of n independent events each with probability P is P^n

your equation is ambiguous. Is it:
\sqrt x + 4 = 3

Good question. Clearly a single metal bar will produce a tone when struck and the frequency of a tuning fork is a function of the single tine length. I have two theories about why two tines are used:...

Nothing will happen unless there are external forces applied to the bar. ;)

Ok. shygrneyzs' answer is essentially correct but the explanation is poor. Let's get our terminology correct. If we answer questions using the wrong terms we'll only make the original poster more...

I already answered your question here: https://www.askmehelpdesk.com/mathsciences/averagespeeedman156364.html but I agree with terryg752.
I'm not really sure what KISS is thinking, certainly...

note the following four facts:
125 = 5^(something)
(a^b)^c=a^(b*c)
a^b * a^c = a^(b+c)
a^b / a^c = a^(bc)

The way to go is to convert all vectors into their x and y components and then just add all the x and add all the y and then convert that pair into a magnitude/direction.
For example, for the 15 N...

Average speed is simple to calculate. Take the total distance traveled and divide it by the total amount of time elapsed.
So, in your case you have 31 pieces of data which are each 1/60th of a...

I won't explain each line. I will answer specific questions you might ask though.

Give everything a common denominator, add/subtract the numerators and then reduce the result

Yeah, clearly a normal pendulum's period is not a function of time.

What sort of question is this? Either it's homework, in which case we don't do your homework for you but we can help with specific difficulties you're having, or... well I can't really think of...

pow is defined as:
double pow(double x, double y);
so the two integers you supply, 10 and I, are cast into doubles, the function is evaluated and a double is returned. When that double is then cast...

I don't even think that you've asked a question.
Also, we will only help with homework, not do it for you.

if you supply a method to determine the value of knowledge and human life I'll let you know. Until then that is a question that each person must answer for themselves.
